Materials World August 2019

2D materials represents a relatively new area of science. The isolation of graphene as a single layer in 2004 fired up interest in the nanoscale, and projects on monolayer materials grew in large numbers, seeking to understand more about the property changes between 2D and 3D structures, for applications relating to everything from energy generation to stronger sportswear. While graphene is the core material of this group, in this issue we take a broader look at current research into 2D materials at large.

van der Waals forces hold atoms together and while weak by nature, they have been found to have powerful effects. We speak to a team of researchers experimenting with 2D crystal stacking and rotation to create artificial van der Waals forces that cause new states of matter and produce materials with unexpected chemical properties. Read more on page 26.

We find out how molybdenum disulphide is enabling quasi-2D gold depositing, hear the latest progress in transition metal dichalcogenides for electrochemical devices, learn how the range of organic molecular building blocks and surfaces offers a ‘near-infinite’ choice of 2D structures, and IOM3 past President, Colin Humphreys, talks about making graphene wafers at commercial scale.

Added to this, we hear about the high demands of materials for gaskets and seals in aerospace, speak to former ICT Scottish branch President, Mary Lawson, about her career in clay, and get an update on the Flexible and Mobile Economic Mineral Processing project.

Let us know what you think.
